I wonder if that's true. There's only one power unit - why not use the wheels to shorten the take-off run ?
But you're probably right - might be difficult, or even dangerous, to supply power to both drive trains as the same time..

Here's their spec: http://www.aeromobil.com/specification.

>There was a light-plane chase plane taking some of that video, and visible in some parts going at the same speed as the prototype. Even if it's a Piper Cub cruise is about 120kph, if it's a Cessna 180 etc. could be up to 200.

But the stall speed is less than 40 knots. And in the clip it's being visibly overtaken by a car in the background. Seems like the specs (max. ground 100mph, max air 124mph) differ from what is quoted in the article anyway.

Interesting that it has variable attack wings (but still a very high Vr at 90mph). Must admit the cockpit looks pretty professional though.
